Abstract
PROCEDIMIENTO E HILERA PARA LA EXTRUSION DE TUBOS DE MATERIAL TERMOPLASTICO. EL MATERIAL TERMOPLASTICO ES EXTRUIDO A TRAVES DE UNA HILERA REDONDA, QUE COMPRENDE UN CANAL ANULAR DIVERGENTE (4), ENLAZADO DIRECTAMENTE A UN CANAL RECTO ANULAR DE CONFORMACION (5), QUE PRESENTA UNA ZONA ANULAR DE PASO ESTRECHADA (10) AGUAS ARRIBA DE SU ORIFICIO DE SALIDA, DE TAL MODO QUE LA VELOCIDAD DE DEFORMACION DEL MATERIAL TERMOPLASTICO EN LA ZONA ANULAR DE PASO ESTRECHADA (10), SEA AL MENOS IGUAL A 0,1 SEGBS-1. A ESTE EFECTO, SE UTILIZA UNA HILERA REDONDA, EN LA QUE LA RELACION ENTRE LA SECCION DE PASO AGUAS ARRIBA DE LA ZONA ANULAR DE PASO ESTRECHADA Y LA SECCION DE LA ZONA ANULAR DE PASO ESTRECHADA, QUEDA COMPRENDIDA ENTRE 1,5 Y 10. EL PROCEDIMIENTO Y LA HILERA CONVIENEN ESPECIALMENTE PARA LA PRODUCCION DE TUBOS DE GRANDES DIAMETROS, SUPERIORES A 250 MM.
